Abstract: 1,010,311. Aerials. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 16, 1963 [Jan. 19, 1962], No. 1991/63. Heading H4A. In a U.H.F. ferrite rod aerial wherein a coupling loop 2 and a part of the ferrite rod 1 are enclosed in a longitudinally split sleeve 4, the uniform capacitance existing (i.e. self capacitance) or placed across the split 5 is arranged in conjunction with the inductance of the sleeve 4 to cause the sleeve 4 to be resonant at the average operating frequency of the aerial and to provide improved matching and sensitivity. The length of the ferrite rod is at least five times greater than its diameter and between 65 and 90% of its length is enclosed by the sleeve 4. The capacitance may be provided by lipping the edges of the slit, Figs. 4 and 5. Preferably, only a single turn coupling loop is used and this may be disposed in a circumferential groove in the rod or in a gap between a two-part ferrite rod (Fig. 3, not shown). Alternatively, the coupling loop may comprise a two-wire transmission line, connected to the sleeve as shown in Fig. 4, or a coaxial cable, Fig. 5, with the outer conductor 10 connected to the sleeve 4 at a point diametrically opposite the split, and the inner conductor 11 connected to the sleeve at a point between the split and the entry point of the coaxial cable. Alternately, the feeder may be taken out through an axial hole in the ferrite rod.

Title: Improvements in the destructive hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1931-01-21
Abstract: Carbonaceous materials are destructively hydrogenated in the presence of a catalyst containing one or more complex compounds of molybdenum or tungsten or both, in the molecules of which more than one radicle containing oxygen and one of the said metals is present.  Compounds specified include the isopolymeric acids of molybdenum or tungsten or their salts, such as ammonium decamolybdate, ammonium pentadecamolybdate, the polymolybdates obtained by heating ammonium paramolybdate, and ammonium metatungstate; the heteropolymeric acids of molybdenum or tungsten or their salts, such as ammonium phosphomolybdate, ammonium silicomolybdate, ammonium tungstomolybdate; the heteropolymeric acids containing molybdenum or tungsten and having a trivalent central atom, or their salts, such as ammonium hexamolybdochromite and ammonium hexamolybdoaluminate. Admixtures of non-reducible substances such as alumina, chromic oxide, kaolin, and the phosphates of zinc, magnesium, and aluminium may be employed.  Any additions of a basic nature must be in such proportion that the predominating components in the final mixture are acid.  The use of paramolybdates and paratungstates is disclaimed. Examples of the production of catalysts are: (1) equal parts of yellow ammonium phosphomolybdate and secondary zinc phosphate are stirred to a paste, dried, comminuted, and reduced with hydrogen at 200 atmospheres and 450 DEG  C.; (2) equal parts of yellow ammonium silico-molybdate, alumina hydrate, and kaolin are made into a paste with nitric acid and dried to 470 DEG  C. until no more nitrous fumes are evolved; (3) equal parts of tungstic anhydride and 3,5 per cent phosphoric acid are mixed to a paste, dried to 400 DEG  C., comminuted and reduced in hydrogen; (4) equal parts of ammonium pentadecamolybdate and alumina hydrate are stirred to a paste with nitric acid, dried, comminuted, and reduced with hydrogen; (5) ammonium hexamolybdochromite and an equal amount of alumina hydrate are made into a paste with nitric acid, cast in moulds and reduced with hydrogen.

Title: Improvements in or relating to recording arrangements
IPC: E21F17/18
Filed: 1959-01-20
Abstract: 890,122. Recording-apparatus. SIEMENS & HALSKE A.G. Jan. 20, 1959 [Feb. 6, 1958], No. 2099/59. Class 106 (4). Recording-apparatus comprises a shaft, which rotates continuously during recording and which carries a recording member K extending helically along the axis of the shaft, a blade D which is controlled by an operating magnet M in such a way that, when the magnet is energized, the blade D is moved towards the recording member K, and means for moving a record strip P, in a direction perpendicular to the axis of the shaft, between the blade and the recording member K, wherein the operating magnet M is connected in series with a buzzer W which repeats the signals audibly. The member K prints on the strip P through a typewriter ribbon Z. To prevent double recording when the beginning or end of the member K is reached, two operating magnets may be used selectively to apply printing pressure on one side of the member K at a time, the selection being controlled by a cam in the shaft of the member K thus depending on the angle through which it has turned. The length of the marks may be kept uniform regardless of the lengths of the signals by using a relay circuit in which only a short-term response of the relay controls the magnet M. Two recording members may be provided on one shaft.

Title: Improvements in electrical force measuring systems
Inventor: THORSSON MATTHEW THEODORE WESL
IPC: G01G3/145
Filed: 1957-01-21
Abstract: 859,431. Electric selective signalling systems. FAIRBANKS, MORSE & CO. Jan. 21, 1957, No. 2127/57. Class 40 (1).  Voltages derived from strain gauge bridges 18, 19, associated with a weighing platform &c. corrected for the weight of the platform by an additional voltage from a potential divider 21 are opposed by the voltage drop in a network 31 supplied via resistors R128 ... R1 which are connected upon turn in ascending order of resistance (so that the values of opposing voltages are in descending order) by a series of relays, the resistor which causes the opposing voltage to exceed the gauge voltage being cut out before the next higher valued resistor is connected in. Detailed operation.-Momentary operation of a start key 73 releases any energized weight registering relays and energizes magnet 53 which closes contact 49 to connect up stepping magnet 52 of a uniselector 60 ... 63. Subsequently, relay 52, which is sluggish, and magnet 52 which has an interrupter contact 75 interact to drive the switch until wiper 63 again reaches its dead terminal. In position b, relay 40, which responds in accordance with the phase sense of the signal from the strain-gauge bridges and the opposing network energizes K128 to connect up resistor R128 and produce the largest step of opposing voltage in network 31. If this represents a weight larger than that on the scale pan, the phase sense of the signal is reversed, relay 40 changes over its contact, and relay K128A pulls up, opening the locking circuit of K128. In position c, relay K64 connects up the next higher resistor R64 and if the balance voltage now applied is smaller than the strain gauge voltage, no circuit is made for K64A and K64 remains locked up when the uniselector moves to position d. The cycle continues so that any relay causing the relay 40 to move to the right is unlocked and the next relay is connected up. When exact balance is achieved, no circuit is made by relay 40 and the uniselector moves to its normal position leaving a selection of relays K128 ... K1 locked up. The locked up relays energize a corresponding selection of relays 65 ... 72 to control an adding machine which as each relay of the series is energized adds an appropriate number to the count. The voltages successively introduced may represent weights in a binary sequence, e.g. 256, 128, 64, &c. units as claimed in Specification 859,432 which is referred to.

The passes are separated by baffle walls 53, 55 comprising tubes 89, the spaces between which are filled with refractory material. Pass 75 contains the auxiliary superheater 125 and the vapour generating tube banks 113, 115. Pass 77 contains the tube bank 63. Pass 79 contains the main superheater 129 and the tube banks 113, 115. Cooling air enters the casing at the rear and flows round the boiler to the front where it is fed to the burners. Adjustment of the three dampers together with a fourth associated with an economiser is effected from a single hand wheel, not shown, mechanically connected to the dampers.
Patent GB-790956-A (GB)
Title: Improvements in or relating to a method of producing tachysterols and derivatives thereof
IPC: C07C401/00
Filed: 1956-01-23
Abstract: Tachysterols and esters thereof are obtained by treating a neutral or weakly alkaline solution of precalciferol or an ester thereof with a catalyst known to be capable of converting cisisomers into trans-isomers.  Iodine or eosine may be used as catalyst, the conversion being effected under the action of light. As starting compounds there may be used precalciferol-2 or precalciferol-3 or esters thereof.  These may be in the form of the product obtained by ultraviolet radiation of a solution of a 3-hydroxy-D 5,7-sterol or an ester thereof from which any unreacted 3-hydroxy-sterol or ester thereof has been removed. Solvents for the reaction are petroleum ether, ligroine, benzene, toluene, cyclohexane, diethyl ether and carbon disulphide. Preferably an acid-binding agent such as pyridine, collidine or quinoline is added.  The tachysterol can be isolated by crystallization as an ester of 3,5-dinitro-4-methyl benzoic acid. Dihydrotachysterol is obtained by subjecting tachysterol to reduction with an alkali metal and an aliphatic alcohol, e.g. sodium and propanol, 2-methyl-butanol-2, ethylene glycol or glycerol.  Examples describe the preparation of tachysterol-2, dihydrotachysterol-2 and dihydrotachysterol acetate.

Title: Improvements in or relating to rotary duplicating machines
IPC: B41L11/00
Filed: 1961-01-19
Abstract: 902,077. Copying documents. RITZERFELD, W., and RITZERFELD, G. Jan. 19, 1961 [Feb. 9, 1960], No. 2191/61. Class 100 (2). Stopping, starting, &c.-A rotary duplicating machine for printing whole pages, lines or sections from a master sheet on to a copy sheet comprises a drum for carrying the master sheet and a single-revolution clutch for coupling the drum to a drive, the clutch being operable by an electromagnet energizable by an electronic element controllable by a plurality of photo-electric cells arranged for sensing a plurality of markings on the copy sheet, when the magnet is energized to close the clutch. A pawl member 11 is pivoted to the drum 1 by a pin 10, and is normally held against a rubber buffer 15 on the drum by a release member 14 pivoted at 16 to the machine frame and released on energization of an electromagnet 20 to allow the drum to make one revolution, at the end of which a lever 21 also pivoted at 16 moves under spring action behind a roller 23 on the drum to prevent reverse rotation of the latter. Two photo-electric cells 31, 32 are arranged in combination with two lamps 29, 30 to sense two markings 34, 35, one near either side of a copy sheet 33 before the latter reaches feed rollers 27, 28. When the light to both cells is cut-off by a marking, the control grid of a gas-filled discharge triode is rendered positive by means of an amplifying valve, so that the triode is ignited and causes the magnet to be energized. If the copy sheet is fed incorrectly, only one mark is sensed at one time, and although the negative grid bias is reduced, the triode does not ignite. The magnet can also be energized by a switch operated manually or by a pedal.
